摘　　要：在大规模无线传感器网络中,针对无线传感器网络中LEACH分簇路由算法能量消耗不均衡,网络生命周期短等问题,提出了一种基于无线射频能量收集的LEACH异构分簇路由算法(LEACH-RFEH)。该算法根据网络中节点剩余能量和当前无线射频补给能量制定了异构无线传感器网络簇头选取机制,高级节点具有无线射频能量收集功能,具有较高的剩余能量和补给能量的节点有更多的机会当选簇头。仿真结果表明:该算法与传统LEACH算法、SEP算法相比,不仅能够均衡网络消耗,而且可以延长网络的工作时间,具有较好的扩展性。Aiming at the problems of unbalanced energy consumption and short life cycle of network in large-scale wireless sensor networks, a clustering routing algorithm for wireless RF energy harvesting based on heterogeneous LEACH（ LEACH-RFEH） is presented. According to the residual energy of nodes in the network and the current wireless radio frequency energy supply,the algorithm selects the cluster head of heterogeneous wireless sensor networks,in which the advanced nodes have the function of wireless radio frequency energy collection,and the nodes with higher residual energy and recharge energy have more chances to be elected as cluster heads. Simulation results show that the presented algorithm can not only balance network consumption,but also prolong the working time of the network,and has better scalability compared with the traditional LEACH algorithm and SEP algorithm.
